Abstract (en)
An OLED display substrate, a manufacturing method of the OLED display substrate, and a display apparatus are provided. The OLED display substrate includes: a first blue OLED light-emitting layer covering an entirety of an active area of the OLED display substrate; one or more additional blue OLED light-emitting layers arranged in a stacking manner with the first blue OLED light-emitting layer; and a quantum-dot color film layer on a light-exiting side of the first blue OLED light-emitting layer and the one or more additional blue OLED light-emitting layers, wherein, a wavelength of blue light emitted by at least one blue OLED light-emitting layer among the one or more additional blue light OLED light-emitting layers is different from a wavelength of blue light emitted by the first blue OLED light-emitting layer.
